Description

Technical Field

[0001] This application relates to the field of loudspeaker manufacturing technology, and more specifically to a loudspeaker assembly positioning and welding device. Background Technology

[0002] In the production of tweeters, the assembly and positioning soldering of the diaphragm and support are crucial steps. Existing fixtures are mostly ordinary cylindrical shapes, which can be used to position the support, but they have several problems:

[0003] 1. The fixture lacks flexibility and has large dimensional tolerances when matching the bracket. When the inner diameter of the bracket is too large, the assembly with the fixture becomes loose, affecting the efficiency of the production line; when the inner diameter of the bracket is too small, assembly becomes difficult and easily leads to damage to the bracket.

[0004] 2. The fixture does not distinguish between positive and negative terminals to prevent mistakes. When assembling the diaphragm assembly, it is easy for the positive and negative terminals of the diaphragm assembly to be reversed with those of the bracket, causing the speaker to be scrapped due to poor polarity and increasing production costs.

[0005] 3. After the diaphragm and bracket are assembled, the position of the wires is difficult to fix. In the subsequent soldering station, the wires are prone to not being properly soldered to the terminals on the bracket, resulting in no conductivity and no sound after soldering, which affects the product quality. Utility Model Content

[0006] This application aims to address the deficiencies in the prior art by providing a speaker assembly positioning and welding device.

[0007] This application discloses a loudspeaker assembly positioning and welding device. The loudspeaker assembly includes a bracket and a diaphragm assembly. The diaphragm assembly includes a diaphragm, a voice coil, and wires. The wires include a positive wire and a negative wire. The device includes:

[0008] The inner ring ring, the outer ring ring surrounding the inner ring ring, and the positive and negative positioning components respectively disposed on both sides of the outer ring ring, wherein the inner ring ring has a plurality of first notches and the outer ring ring has a plurality of second notches, and the positive positioning component and the negative positioning component are different.

[0009] The outer ring member is configured to be inserted into the bracket to position the bracket.

[0010] The inner annular component is configured to be inserted into the voice coil to position the voice coil;

[0011] The positive electrode positioning component is configured to position the positive terminal of the bracket and the positive electrode wire;

[0014] In some alternative embodiments, the device further includes a positioning through-hole passing through the center of the inner annular member and through the chassis, configured to engage with an external device.

[0015] In some alternative embodiments, an annular cavity for accommodating the voice coil is formed between the inner annular member and the outer annular member.

[0016] In some alternative embodiments, both the inner and outer annular components are made of elastic materials.

[0017] In some alternative embodiments, the upper surface of the inner annular member is higher than the upper surface of the outer annular member.

[0018] In some alternative implementations, the number of the first gap and the number of the second gap are equal and correspond one-to-one.

[0019] In some optional embodiments, the positive terminal positioning component includes a positive terminal slot for positioning the positive terminal and a positive wire slot for positioning the positive wire, and the negative terminal positioning component includes a negative terminal slot for positioning the negative terminal and a negative wire slot for positioning the negative wire.

[0023] 1. Precise positioning of the voice coil inner diameter and the support inner diameter: The inner ring is inserted into the voice coil of the diaphragm assembly to position the voice coil; the outer ring is inserted into the support to position the support. Simultaneously, multiple notches are made on both the inner and outer rings to increase the jig's flexibility, preventing overly tight or loose assembly due to inner diameter tolerances. This improves positioning accuracy, assembly efficiency and quality, and enhances assembly stability and reliability, reducing production line difficulties and potential quality issues.

[0024] 2. Differentiate between positive and negative terminals to prevent mistaken connection: Set up positive and negative terminal positioning components, and the two are different. In this way, the positive and negative terminals can be distinguished, and corresponding mistaken connection can be achieved to avoid the speaker being scrapped due to incorrect polarity assembly.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0040] The following detailed descriptions will be provided through specific embodiments.

[0041] To address the problems in the prior art, this application proposes a speaker assembly positioning and welding device.

[0042] refer to Figure 1 The loudspeaker assembly 10 of this application includes a bracket 11 and a diaphragm assembly. The diaphragm assembly includes a diaphragm 12, a voice coil 13, and wires. The wires include a positive wire 14 and a negative wire 15.

[0043] refer to Figures 2 to 5 The speaker assembly positioning and welding device 20 of this application includes: an inner ring ring 21, an outer ring ring 22 surrounding the inner ring ring 21, and a positive positioning component 24 and a negative positioning component 25 respectively disposed on both sides of the outer ring ring. The inner ring ring 21 has a plurality of first notches 2101, and the outer ring ring 22 has a plurality of second notches 2201. The positive positioning component 24 and the negative positioning component 25 are different.

[0044] The outer ring member 22 is configured to be inserted into the bracket 11 to position the bracket 11.

[0045] The inner ring 21 is configured to be inserted into the voice coil 13 to position the voice coil 13;

[0046] Positive positioning component 24 is configured to position the positive terminal 1101 and positive lead wire 14 of the bracket 11;

[0047] The negative electrode positioning component 25 is configured to position the negative electrode terminal 1102 and the negative electrode wire 15 of the bracket 11.

[0048] In some alternative embodiments, the device 20 of this application further includes: a chassis 26 configured to carry an inner ring member 21, an outer ring member 22, a positive electrode positioning assembly 24, and a negative electrode positioning assembly 25.

[0049] In some alternative embodiments, the device 20 of this application further includes a positioning through-hole 27, which passes through the center of the inner annular member 21 and through the chassis 26, and is configured to engage with an external device. The external device includes, for example, a dispensing device (or glue applicator). The device 20 of this application can be positioned and connected to the dispensing device via its positioning through-hole 27, and can rotate under the control of the dispensing device to dispense glue onto the bracket 11 and the diaphragm assembly.

[0050] In some alternative embodiments, an annular cavity 23 for accommodating the voice coil 13 is formed between the inner annular member 21 and the outer annular member 22. The width of the annular cavity 23 is greater than the thickness of the voice coil 13, and the depth is greater than the height of the voice coil 13.

[0051] In some optional embodiments, both the inner annular component 21 and the outer annular component 22 are made of elastic materials, such as plastic steel. Thus, the inner annular component 21 and the outer annular component 22 possess a certain degree of elasticity. Combined with the first notch 2101 and the second notch 2201 formed on both, the elasticity is further enhanced, allowing for a certain degree of deformation. This avoids overly tight or loose assembly during positioning due to tolerances in the inner diameter, improving positioning accuracy, assembly efficiency and quality, and enhancing assembly stability and reliability, while reducing difficulties in production line operations and potential quality issues.

[0052] In some alternative embodiments, the upper surface of the inner annular member 21 is higher than the upper surface of the outer annular member 22. Of course, depending on the structural dimensions of the speaker assembly, the upper surface of the inner annular member 21 may also be lower than or equal to the upper surface of the outer annular member 22.

[0053] In some alternative implementations, the number of first notches 2101 and second notches 2201 are equal and correspond one-to-one (or, the number may be unequal and not correspond one-to-one).

[0054] In some alternative embodiments, the positive terminal positioning component 24 includes a positive terminal holder 2401 for positioning the positive terminal 1101 and a positive wire holder 2402 for positioning the positive wire 14, and the negative terminal positioning component 25 includes a negative terminal holder 2402 for positioning the negative terminal 1102 and a negative wire holder 2502 for positioning the negative wire 15.

[0055] In some alternative implementations, the positive electrode positioning component 24 and the negative electrode positioning component 25 are different, which may be different in shape, or one of them may have a marking element 2403 on its surface.

[0056] In some alternative embodiments, the positive electrode positioning component 24 has an identifier 2403 for distinguishing it from the negative electrode positioning component 25. The identifier 2403 includes, but is not limited to, a colored coating, or engravings, scratches, or a film, or an adhesive, etc.

[0057] In some alternative implementations, the negative electrode positioning component 25 may have an identifier 2403 for distinguishing it from the positive electrode positioning component 24.

[0058] In some alternative embodiments, the device 20 of this application is a one-piece molded structure, such as one-piece injection molding.

[0059] The above provides a brief overview of the structural composition of the device 20 of this application. Its characteristics will be further described below.

[0060] The device 20 of this application has its inner ring 21 and outer ring 22 made of a material with a certain degree of elasticity, such as plastic steel, to ensure that it can adapt to the tolerance range of the inner diameter of the bracket 11 and the voice coil 13 during assembly, avoiding assembly that is too tight or too loose. The positive electrode positioning component 24 and the negative electrode positioning component 25 are precisely machined to ensure accurate positioning of the positive and negative terminals and wires.

[0061] During assembly, the outer ring component 22 is first inserted into the bracket 11 for initial positioning. Then, the inner ring component 21 is inserted into the voice coil 13 of the diaphragm assembly for positioning. Next, the positive terminal 1101 of the bracket 11 is inserted into the positive terminal slot 2401 of the positive terminal positioning component 24, and the positive wire 14 of the diaphragm assembly is inserted into the positive wire slot 2402 of the positive terminal positioning component 24. Similarly, the negative terminal 1102 of the bracket 11 is inserted into the negative terminal slot 2501 of the negative terminal positioning component 25, and the negative wire 15 of the diaphragm assembly is inserted into the negative wire slot 2502 of the negative terminal positioning component 25. Finally, the assembled diaphragm assembly and the bracket 11 are placed together on a fixture for gluing and welding.

[0062] During the welding process, the wires are accurately aligned with the terminals on the bracket 11 by the positive electrode positioning component 24 and the negative electrode positioning component 25, resulting in a good welding effect. Problems such as non-conductivity or no sound caused by incorrect welding of the wires to the terminals will not occur. At the same time, the flexible design of the device makes the assembly of the bracket 11 and the voice coil 13 smoother, and will not cause assembly difficulties or loosening due to inner diameter tolerances, thereby improving production efficiency and product quality.

[0063] The technical solution of this application has been described in detail above through specific embodiments. In the above embodiments, the descriptions of each embodiment have their own emphasis, and for parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.
